Electro-optic apparatus, driving method for the same, and electronic appliance

An electro-optic apparatus, comprising:

• a plurality of scan lines;
• a plurality of data lines that intersect the scan lines;
• pixel electrodes disposed at respective intersections of the scan lines and the data lines;
• a counter electrode disposed opposite the pixel electrodes, the counter electrodes being set at a predetermined potential;
• electro-optic material disposed between the respective pixel electrodes and the respective counter electrodes,
• a memory to store logic corresponding to a tone of a data signal supplied from the data lines to the pixel electrodes in accordance with logic of a polarity signal;
• a power supply selecting device, the power supply selecting device switching between a first state in which a first potential and a second potential are supplied to the memory and a second state in which a third potential and a fourth potential are supplied to the memory, based on a switching of the logic of the polarity signal;
• and
• a reading device to switch a read of logic stored in the memory device based on the switching of the logic of the polarity signal, and supplying the pixel electrodes,
• the predetermined potential being lower than the first potential and the second potential and being higher than the third potential and the fourth potential.
